| Abstract: | In this paper the"penalty function"method based on constrained variational principle is applied to modify the constrained conditions in imbedding and contact problems of three-dimensional joint elements, with the modified contact stiffness and contact load vector derived. Also presented is a program chart showing how to use the incremental finite elements method to solve the contact problems of three-dimensional joint elements |
